AUTOMATIC DOSER AND SELF-FEEDER.

Specification of Letters Patent.

Patented Nov. 8, 1921.

Application led March 17, 1920. Serial No. 366,566.

To all whom it may concern:

Be it known that I, JAMES W. CoRiNGroN, a citizen of the United States, residing at F aucett, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Automatic Dosers and Self-Feeders, of which the following is a specification.

My invention relates to a self-feeder and automatic doser for hogs, sheep and other domestic animals, and one object is to provide an apparatus of this character which will exclude small animals and fowls from the feed but in which said feed is readily accessible to larger animals such as hogs, sheep, ete.

Another object is to provide an apparatus of this character in which a dose of tonic or medicine may be automatically fed to a hog or other animal, and means by which the amount of said dose may be regulated.

A further object is to provide an oiling device in combination with the self-feeder, by means of which hogs and: other animals on approaching the troughs of said selffeeder are supplied with crude oil or the like for ridding them. of lice, mange, etc.

A further object is to provide automatic means for preventing the self feeder from becoming clogged and thereby failing to function properly.

lVith the above and other objects which will hereinafter appear, reference will now be had to the accompanyingdrawings, in which:

Figure l is a side elevation of the apparatus.

Fig. 2 is an end elevation of the apparatus.

Fig. 3 is a vertical cross section through the automatic doser, on line III-III of Fig. 1. y

Fig. 4 is a vertical cross section through Y the feeder, on line IV-IV of Fig. 1.

Fig. 5 is a fragment of one end of the apparatus.V

Fig. 6 is a broken detail elevation of cer# tain of the valves and'associated mechanism, for regulating the size of the dose of tonic or medicine.

Fig. 7 is a cross section on line VII- VII of Fig. 6. y Y

In carrying out the invention, I employ a bin 2 embodying a top 4, sloping sides 6 and a bottom 8. The upper portion of the bin is provided with a lid 8a connected to the top 4 by hinges 10. The bin 2 is divided by a vertical partition 12 into a relatively large feed compartment 14 and a smaller medicine or tonic'compartment 16. The .bottom 8 of the bin 2 is provided with longitudinal diverting guide boards 18, which direct the feed into troughs 2O through openings V22 extending longitudinally of the lower portions of the sides 6. Platforms 24 extending beneath the troughs 2O are provided for the animals to stand upon'yvhile feeding.

The compartment 14 is provided with agitators 24 to prevent the feed from becoming clogged therein. Said agitators embody oppositely-disposed rock shafts 26 extending longitudinally through the upper portion of the bin and journaled in the ends thereof. Each shaft 26 is provided at its ends with iiXedly-mounted arms 28, the arms connected to one shaft crossing the arms on the other shaft, as disclosed on Fig. 2, and con- .to Vlimit the downward movement of the arms,28.

The pipes 30 areY provided at their under portions with longitudinalslots in which wicks 32 ai'e placed. The pipes 30 are connected to sections of hose or other flexible tubing 34, arranged adjacent to one end of the bin 2 and connected at their upper ends to a Tcoupling 36, which in turn is connected to a supply pipe 38 leading from the bottom of a tank 40 containing a liquid remedy such as crude oil for lice, mange, etc. The How of liquid through the supply pipe 38 is controlled by a valve 42.

Fowls and small vanimals are prevented from gaining access to the feed in the troughs 2O by guards 44 swingably connected to the sides 6 of the bin by hinges 46. As shown more clearly on Fig. l, each trough 2O is provided with two guards 44, which depend over the front edges of said troughs 2O and are spaced from each other by suitable partitions 48. By hanging the guards 44 from the hinges 46 as shown and described they may be yreadily pushed backwardly to open position by a hog, against the sloping sides 6 of the bin 2 and expose the feed in the troughs 2O.

When the guards 44 are in closed position as shown more clearly on Fig. 4, fowls and small animals are prevented from gaining access to the ends of the troughs 20 by shields V"50' and 52; The shields 50 are fixed to the sides 6 of the bin 2, near one end of the latter, while the shields 52 are 4secured to the ends of the guards 44 adjacent to the oppoite end of the bin 2, as disclosed on Figs. 1 and 5. The free edges of the shields 52 i Y extend beneath keepers 54, fixed to the adj acent end of the bin 2 anda-re prevented by said keepers 54 from being pryed off their respective guards`44 by fowls `and small animals. f

Referring .now more particularly to the compartment 16` and its mechanism shown more. clearly on Figs. 3, 6 and 7, 56 designates a'hopperin the upper portion of said compartment 16 for yholding Vmedici-ne or tonic in powder or granularv form. The bottom of the 'hopper 56 communicates with two measuring tubes 58 leading down to the inverted V-shape'd bottom 60 :of the -compartinent 16. The bottom60 slopesin op'- posite directions to openings 62 in the sides 6v of the bin 2. Said openings 62 communicate with cups 64, which project over swingf bin 2.

ing platforms 66 mounted on pivots :68 secured to thel lower portion of the bin 2.

v'Iheineasuring tubes-58 are firmly secured Y to the partition 12 by a plate 69, provided at its upper `and lower portions with outturned flanges 70 in Vwhich thetubes 58 are fixed and rock-shafts@ are journaled. rock-shaft 72 is vprovided at its upper portion with an arm .7 4, carrying a valve 7 6 operating through a slot 7 8 in the associated,

tube 58 and normally held in closed position by avvco'il spring 79. rIhe lower portion of each shaft .72 is provided with a series of arms 80, any one of which is adapted to receive a valve 82 providedwith a set screw 86. whereby it is removably secured in position. 'The valve 82 is` adapted to enterany of the slots 88 inthe associated tube 58;

l' As shown Ymore clearly on Fig. 6, the valve 82 is mounted in the present instance on the Vupper arm 80 to permit a minimum dose to pass through` the associated tube 58.k If'a larger dose is desired, thevalve82 is removed to the intermediate arm 80, and if the maXimum doseis desired said valve 82 is placed on Vthe lowermost arm 80.

Accessis gained 4to thevalves 7 6 and 82 through a door 89 in the adjacent end of the yThe roclr shafts V72 are'l provided with cranks 90 to which chains 92 are connected at one end, the opposite ends of said chains being connected to bell-cranks 94 mounted on pivots 96 supported by the partition 12:

OneV arm ofy each bell-crank 94 projects through a slot 98 inthe adjacent wall 6 of the bin 2 and is connected to a chain or other cable 100, extendingdownwardly and connected at its lower end to a fastening- 102 fixed to the associated platform 66. The chains 100` are protected vfrom contact with Each the hogs by sheet metal guards 104 fixed to the shields 50.

ine operation in general is as follows? The lid 8au is raised and the compartment 14 Y is supplied with feed,rwhile the hopper 56 is supplied with medicine or tonic. As a hog steps upon one of the platforms 24, he swings the adjacent guard 44 inwardly to gain access to the feed, while his back rubs against the wick 32Vand is thereby coated with the crude oil or other liquid remedy in he pipe 80.- Healso raises the pipe80 and actuatesV the associated agitatorH 24V through the Vintermediacy of the arms-28, so

that in case the feed has becomeclogged it will be :loosened and'flow freelyV tothe troughs 20. If thehogdesires a dose of tonic or medicine vhe istepsupon onev of the platforms 66 to gain accesspto one ofthe cups 64and in so .doingdepresses said platform .'66, which' through the intermediacy `of the connecting'mechanisnn rocks the asso-l ciated -shaft,.causing it to swing the upper valve 7 6 to yopen` position and close the lower valve 82. A portion of the medicine inf the hopper V56 then flows downwardly andzfills the tube 58 to the depth of the lower valve 82. .After the hog has partalrenof `the medicine in the .cup and steps .off the platform 56, the spring 79 .immediately rocks Vthe shaft 7 2, which closes the upper valve 7 6 Vand opens the lower valve 82, so that the meas-V ured Vcharge of medicine between said valves may pass downwardly through'the tube 58 and into the cup.64. Y'

From the foregoing description, it will 'be apparentthat I have produced an apparatus embodying the advantages above set forth, and while I have shown and described the preferred construction, combinationV and `arrangement of parts, reserve the'right to make suoli changes .as properly fall within the spirit and scope of the claims.

Having thus described my. invention, what I claim and desire.to vsecure by Letters Patent, is: Y
